Abstract
A silicone extrusion plant has a silicone extruder and a silicone feed device configured to load the silicone extruder. The silicone feed device has a feed hopper. The feed hopper opens into a feed opening at the bottom thereof. The feed opening is in a fluidic connection, via a feed duct, with an inlet zone of the silicone extruder. A feed screw arranged in the feed hopper in such a way as to be drivable for rotation protrudes into the feed opening at least partly. The feed screw has a cone portion and a cylinder portion. According to another aspect, the silicone extrusion plant has at least one feed pressure sensor configured to measure an actual feed pressure of silicone material to be extruded. A control unit is in a signal communication with the feed pressure sensor and a feed drive device in order to drive the silicone feed device.
